We now have good documentation on the PCI NUMA affinity policies
(thanks, artom!) so we can close out this TODO. Hurrah!

This beefy patch closes a long-standing TODO and allows us to move yet
more information out of the flavors guide and into specific documents.
This, combined with existing documentation in place, means we can remove
the sections for various extra specs from the 'user/flavors' guide:
- hw:cpu_realtime -> doc/source/admin/real-time.rst
- hw:cpu_realtime_mask -> doc/source/admin/real-time.rst
- hw:emulator_threads_policy -> doc/source/admin/cpu-topologies.rst
- hw:cpu_policy -> doc/source/admin/cpu-topologies.rst
- hw:cpu_thread_policy -> doc/source/admin/cpu-topologies.rst
- hw:cpu_sockets -> doc/source/admin/cpu-topologies.rst
- hw:cpu_cores -> doc/source/admin/cpu-topologies.rst
- hw:cpu_threads -> doc/source/admin/cpu-topologies.rst
- hw:cpu_max_sockets -> doc/source/admin/cpu-topologies.rst
- hw:cpu_max_cores -> doc/source/admin/cpu-topologies.rst
- hw:cpu_max_threads -> doc/source/admin/cpu-topologies.rst
- hw:numa_nodes -> doc/source/admin/cpu-topologies.rst
- hw:numa_cpus.N -> doc/source/admin/cpu-topologies.rst
- hw:numa_mem.N -> doc/source/admin/cpu-topologies.rst
- hw:mem_page_size -> doc/source/admin/huge-pages.rst
Multiple improvements to the libvirt extra spec docs are included here,
for want of a better place to include them.

Nova and QEMU[1] supports PCI devices with a PCI address that has 16 bit
domain. However there are hypervisors that reports PCI addresses with
32 bit domain. While today we cannot assign these to guests this should
not prevent the nova-compute service to start.
This patch changes the PCI manager to ignore such PCI devices.
Please note that this patch does not change fact that nova does not
allow specifying PCI addresses with 32bit domain in the
[pci]/passthrough_whitelist configuration. Such configuration is still
rejected at nova-compute service startup.

I'm pretty sure this was meant to be physnets given the
context and this was added with Ide262733ffd7714fdc702b31c61bdd42dbf7acc3
which is about provider physical network affinity to NUMA nodes.

In the "Networking with neutron" doc,
a description of a configuration file is broken.
So fix it.

A guest must have a NUMA topology for numa-aware-vswitches to have any
effect. Call this out in the documentation.

Now that we have this information, we can use it as a pre-filtering for
suitable hosts.
With this patch we complete the blueprint. As a result, documentation
and release notes are bundled in the patch and previously inactive tests
are now enabled.
